Double parth extrution
Double parth extrution
(OP)
Hey guys. Im trying to draw something that i think requires the extrution to follow multiple paths, and i do not know of a way to make my AutoCAD 14 do that. I am trying to draw a wing that has a shape of a half ellipse (Ellipse with a flat bottom) that needs to be extruded at an angle and also get narrower on the inside part of the angle as it extrudes. I cannot think of a way to do this without the ability to make the extrution follow multiple (4) paths.
Think of how a wing is shaped on a 50's jet fighter like a Mig 15. The wing starts out the the body. Its rounded on the top side and flat on the bottom to generate lift. Its angled at like 45 degrees towards the back and it gets narrower as it gets farther from the airplne's body. How would you draw that in true 3d with can 14?

the only way you can do is using the surface modelling. I suggest using edgesurf and using multiple surface to achieve the wing model. For your refference, the model will be hollow, not solid.

and use addition and subtraction and you can get very close to what you want just depending on how long you want to spend on it belevie me some one told me that drawing thread like objects in autocad 2000 was impossible and it only took me 2 to 3 weeks to do it

I don't think ACAD can create a solid model of the wing, just a surface model.
As far as Ahraxx's post, I think his instructor is mistaken. Boeing uses Catia (commercial business) and Unigraphics (military, former McDonnel Douglas business).
